PROGRAMMABLE FUNCTIONS
FAULT DETECTION
NOTE: Refer to the manufacturer's operation
manual or website for complete lists and
explanations.
• 1-00 – Maximum Output Frequency
This parameter determines the AC drive's Maximum
Output Frequency. All the AC drive accelerations
and decelerations are scaled to correspond to this
maximum output frequency.
• 1-05 – Minimum Output Frequency
This parameter sets the Minimum Output Frequency
of the AC drive. This parameter must be equal to or
less than the Mid-Point Frequency (50.7).
• 1-09 – Acceleration Time
This is used to set the acceleration time. The
acceleration time is based on the time it takes for
the drive output to reach 60 Hz.
• 1-10 – Deceleration Time
This is used to set the deceleration time. The
deceleration time is based on the time it takes for
the drive output to reach zero speed (from 60 Hz)
after a stop or zero command is given.
• 2-00 – Source of Frequency Command
This is used to set the drive for either keypad control
or external signal input control.
• 2-01 – Source of Operation Command
This is used to set the drive to determine operating
commands from the Digital Keypad or external
signal inputs.
• 7-00 – Motor Rated Current
The value must be between 30 to 120% of the drives
rated output current. This parameter sets the drive's
output current limit.
• 8-00 – DC Brake Voltage Level
This parameter determines the amount of DC
Braking voltage applied to the motor during start-up
and stopping. This value must be between 0% and
30%.
• 8-02 – DC Braking Time upon a Stop
This parameter determines the duration of time that
the DC braking voltage will be applied to the motor
upon a stop command of the AC drive.
• 8-14 - Auto Restart After Fault
After a fault occurs, the AC drive can be reset/
re-started automatically up to 10 times. Setting
this parameter to 0 will disable the reset/restart
operation after any fault has occurred.
FAULT NAME
FAULT DESCRIPTION
CORRECTIVE ACTIONS
The AC drive detects an abnormal
increase in current.
Check the wiring connections between the AC drive and motor for
possible short circuits.
Increase the acceleration time.
Check for excessive loading conditions at the motor.
The AC drive temperature sensor
detects excessive heat.
Make sure the ambient temperature falls within the specified
temperature range.
Remove any foreign objects from the heat-sink, and check for possible
dirty heat-sink fins.
The AC drive detects excessive drive
output current.
Check if the motor is overloaded.
Internal electronic overload trip.
Check for possible motor overload.
Check electronic thermal overload setting.
Motor overload.
Reduce the motor load.
